The upper housing 210 includes a water tank 220 arranged thereon and used for containing a clean fluid therein, an electric motor 230 for providing the negative pressure and a dirt collector bin 240 for containing dirt therein. The dirt collector bin 240 is connected to the suction vent hood 140 via a pipe. The electric motor 230 is connected to the pipe in order to provide the negative pressure and to suck the foreign objects from the suction vent hood 140 to the dirt collector bin 240. The water tank 220 is connected to the nozzle 150 via a pipeline in order to achieve ejecting of water, and the pipeline connected to the nozzle 150 is installed with a pressurizing device for pressurizing the water supplied.

In an embodiment of the present invention, the lower body 100 and the upper body 200 are connected to form a main body of the entire produce and are used for the installation of functional parts while providing appropriate installation structures matching with the shape of each functional part. In addition, they also include derivative structures provided for the installation of each functional part. During the use of the product of the present solution at work, the roller 120 is rolled to complete the cleaning of floor. In addition, during the cleaning process, the roller 120 is attached with dirt and debris. Accordingly, the water tank 220 contains clean water, and through the function of the pipeline and the pressurizing device, after the water enters the nozzle 150, it is ejected onto the roller 120 to achieve cleaning. In general, the outer surface of the roller 120 is water absorbing, and this is mainly due to the reason that water absorbency is one of the essential characteristics for a cleaning tool. Accordingly, when water is ejected onto the roller 120, it is able to achieve the cleaning effect of the roller 120. In addition, with the scraping action of the scraper 130 on the roller 120, it is able to cause deformation on the surface of the roller 120 in order to squeeze out dirty water. Furthermore, under the effect of the negative pressure, the suction vent hood 140 and the pipe are used to suck dirt and debris into the dirt collector bin 240 in order to complete the collection and storage of dirt and debris. The pressurizing device is formed by various types of water pumps and solenoid valves, etc.

In an embodiment of the present invention, preferably, the roller 120 can be a brush roller or a fluffy roller. The brush roller is used for surfaces that are relatively difficult for cleaning, such as carpet. The fluffy roller is for flat floor surface. Preferably, the surrounding to the roller 120 can be selectively arranged with deformable material or structure. For example, the use of foam type of deformable material or deformable structure having a bendable support disposed inside a surface material for installation on the roller 120 in order to facilitate the deformation. In addition, through the use of the scraper 130, scraping can be performed in order to achieve greater use effect of cleaning and scraping.

In an embodiment of the present invention, preferably, the suction vent hood 140 comprises an open hood 141 and an air vent portion 142 arranged at a center of the hood housing 141. The hood housing 141 faces toward the roller 120 and the air vent portion 142 is connected to the pipe. In this preferred embodiment, a preferred structure of the suction vent hood 140 is provided, and through such structure, it is able to perform full water absorption on the roller 120 such that the effect of negative pressure and water absorption can be guaranteed to be achieved.

In an embodiment of the present invention, preferably, the scraper 130 is arranged to extend along an axial direction of the roller 120. In this embodiment, the extending structure of the scraper 130 is able to guarantee the effect of scraping and cleaning.

In an embodiment of the present invention, preferably, an edge of the hood housing 141 is arranged corresponding to an edge of the roller 120. As the edge of the hood housing 141 is aligned with the edge of the roller 120, in this embodiment, since the hood housing 141 corresponds to the roller 120 in order to cooperate with the roller 200, it is able to perform suction of trash or waste from the roller 120 area completely. The vent pipe 142 is installed to achieve exhaust and to facilitate the structural use, thereby guaranteeing the generation of sufficient negative pressure effect.

The scrapper 130 has a strip shape and is arranged along the axial direction of the roller 120. Preferably, the scraper 130 is arranged along the axial direction of the roller 120 in order to guarantee that trash or foreign objects can be scraped away along the axial direction of entire roller 120. In an embodiment of the present invention, the scraper 130 is arranged to have a length equivalent to that of the roller 120 in order to facilitate the scraping of trash away entirely.

In an embodiment of the present invention, preferably, one side edge of the scraper 130 abuts the roller 120 and another side edge opposite thereto is fixed to the hood housing 141. In this preferred embodiment, one side edge of the scraper 130 is fixed to the hood housing 141, and such arrangement method is able to achieve a higher structural stability and the location adaptability is also higher.
